Yep. Effective advertising is based on repeated impressions. Why billboards work. They’re spreading the meme into the national subconscious ... gratis.
best example of billboard memes were the burma shave billboards on rt 66 back before interstate 40 across the southwest.
My dad was in the army. we drove back and forth between bases on the east coast and west coast in the 1950’s-60’s. those burma shave mile markers came up regularly.
I never shaved with burma shave but the bill boards were memorable.
